It's a search engine for programmers where you can search for queries with symbols in them(e.g. if you search for "&&" it will actually return pages with "&&" somewhere in them, unlike google)

See it here: http://symbolhound.com/

There's still a lot of work to be done (especially in indexing more websites, right now everything besides stackoverflow is very underrepresented, but I plan to fix that over the next few months), but it's already been useful to me.
